Molecular determinants of Smc5/6 association with DNA junctions.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Smc5/6 is an essential genome maintenance complex that interacts with double-stranded (ds) DNA, single-stranded (ss) DNA, and ss-dsDNA junctions. DNA association underlies Smc5/6's functions in managing intermediates generated during genome replication and repair. However, the mechanisms of this activity are not fully understood. Here, we report a single-molecule study examining Smc5/6 association with a dsDNA substrate containing a ssDNA gap with defined 3' and 5' junctions. We found that Smc5/6 associates with both 3' and 5' junctions but prefers the 3' junction in the presence of the ssDNA-binding complex RPA. Further, Smc5/6's junction association frequency and dwell time are regulated by two non-SMC subcomplexes and DNA binding residues of Smc6. Moreover, Smc5/6 prefers binding to junction sites free of the sliding clamp PCNA over those occupied with it. These results suggest that Smc5/6 utilizes its multiple structural modules to associate with junction sites in coordination with other genome maintenance factors.
